Flutter - Support build of multiple BuildTypes

Question

I've created 3 buildTypes at my android project:

buildTypes {
        release {
            signingConfig signingConfigs.release
            resValue "string", "app_name", "AppName"
        }
        debug {
            applicationIdSuffix ".debug"
            resValue "string", "app_name", "AppName - DEV"
        }
        staging {
            initWith release
            matchingFallbacks = ['release']
            applicationIdSuffix ".debug"
        }
    }

I would like to assemble my staging build type, so I ran "flutter build apk --staging", but flutter can't find that option:

Could not find an option named "staging".

Seems that Flutter build apk command "flutter build apk" supports only 3 types : debug, profile, release; and in case of using custom buildType - there's no support for that.

Is it possible to build an apk of custom BuildType?

I ended up using productFlavors:

flavorDimensions 'app'


productFlavors {
        dev {
            dimension "app"
            resValue "string", "app_name", "AppName - DEV"
            applicationIdSuffix ".debug"
        }
        staging {
            dimension "app"
            resValue "string", "app_name", "AppName - DEV"
            applicationIdSuffix ".debug"
        }
        prod {
            dimension "app"
            resValue "string", "app_name", "AppName"
        }
    }

One solution is to use Android's own Gradle build tasks instead of using Flutter commands.

1. cd android/
2. ./gradlew app:build

Then after a succesfull build you should be able to find an apk for each buildType in build/app/outputs/apk/.
